SPECIFICATION forming part of Letters Patent No. 781,910, dated February '7, 1905.

Application filed June 27, 190 i. Serial No. 214,248.

To all whom it may concern:

Be it known that l, ADnLBnR'r L. SAUER, a citizen of the United States, and a resident of Milwaukee, in the county of Milwaukee and State of isconsin, have invented a new and useful Improvement in Skim-Milk and hey eighing Scales, of which the following is a specification.

My invention relates to a weighing device in which the liquid to be weighed is received by a revolving wheel having buckets, which when one is filled with a certain determined amount or Weight of said liquid will cause said wheel to revolve a partial revolution and empty said bucket while another one is brought into proper position for being filled,

mechanism being arranged for operation by and its object is to provide a weighing-scale for butter and cheese factories which is easily operated, will deliver approximately correct weights of such liquid as the persons which supply said factories with milk desire to have returned to them for feeding purposes, and

A which scale can be placed where it is convenient for receiving the liquid by the patrons of the factory, while its weight determining mechanism can be placed entirely under the control of the factory operator, said device being illustrated in the accompanying drawings, in which Figure 1 is an end elevation of that end of the wheel having the larger part of the mechanism for determining the weight of the liquid which is to be delivered. Fig. 2 is an end elevation of the opposite end of the wheel and its mechanism upon that end. Fig. 3 is aside elevation longitudinally of the axis of the wheel and showing the mechanism thereof, the framing upon the right-hand side in Fig. 1 being removed,

Similar numerals and letters indicate like parts in the several views.

The frame of the machine consists of posts 1, cross-girths 2, cover 3, and curved front and rear side pieces or chutes L for conveying liquid from the wheel to the milk-can under neath the machine, the chutes having side flanges 5, the two latter parts being removed in front in Fig. 3 for showing the wheel entire. The wheel is mounted for revolution upon and with the shaft 6 and consists of end disks 7 and 8, having two buckets 9 and 10 formed between them, the buckets being similar in form, adapted to hold a quantity of liquid to be weighed, and entirely emptied of it as the wheel is revolved. Mounted upon the frame-cover 3 is a pipe 11, which is to be connected at its upper end with a supply of liquid to be delivered. A valve 12 is arranged at the lower end of said pipe in the valvechamber 11, through which the liquid can be delivered into the buckets 9 and 10, a guidingehute a being arranged for directing the liq uid into the buckets. Hinged in the hanging bracket 13 upon the pin 14: is a rod 15, which extends over the wheel and is connected by the band 16 and the bolt 16 with the valve. Upon the end disks of the wheel are cams l7 and 18, the former being shown as integral with the disk and the latter as adjustable circumferentially of the disk bymeans of the slots 19 and screw 20. from the cam and rests on the outer edge of the disk. The purpose of the adjustable cam is to lengthen or shorten the time in which the milk will be allowed to run before the valve will close, the position of the cam upon the disk being adjustable circumferential] y of the disk along the slot 19. These cams as the wheel revolves engage the rod 15, lift it, and also the valve. One of the cams may be arranged in position for opening the valve and the other for closing it at the proper time for allowing the desired weight of liquid to enter the buckets of the wheel. The valve which is shown in Fig. 2. is the common cistern-pump valve; but other styles of valves may be arranged for admitting the liquid to the buckets. The cams are shown in position for commencing the opening of the valve. The wheel will revolve in the direction of the arrows, filling and emptying the buckets one after the other as long as a supply of liquid is provided unless its revolutions are stopped by some means.

A lip 21 extends out' The weighing of the liquid so that an equal amount is delivered to each bucket is provided for by means of a lever 22, which is arranged to swing freely upon pin 23 in the bracket-arm 23. Pins 24 project out from the side of the disk 8 for engaging the short arm of the lever,which they will do whenever sufficient liquid is admitted to a bucket, and the wheel will be revolved until a pin strikes the short arm of the lever. As the weight of liquid increases the wheel will revolve until the pin slides off of the short arm of the lever and the liquid is discharged from the wheel. A weight 25 is adjustably secured upon the long arm of the lever for allowing the desired weight of liquid to enter each bucket before said weight will rise sufficiently to allow the pin 24 to slide off of the short arm of the lever and the liquid to be discharged from the bucket. As one bucket is emptied another one is brought into position for receiving liquid.

For assisting in making the revolutions of the wheel continuous and of even speed a governor-lever 26 is hinged within each bucket to a suitable socket, as 27, each socket having a stop 28 for preventing its lever from swinging backward beyond a determined point, said levers being intended to swing outward, as the left-hand one in Fig. 1, and inward, as the right-hand one is shown to be, at just the right time in the revolutions of the wheel for assisting in bringing the buckets into the proper position for receiving the liquid and discharging the same and making the speed of its revolutions nearly uniform.

For the purpose of delivering a certain weight of liquid to a customer one end of a shaft 29 is fixed in the boss 30 of the frame and its other end in a standard 31, having mounted loosely thereon the ratchet-w heel 32. having teeth 33, and integral with said wheel a drum 34, and also having the rope-pulley 35, with a drum 36 integral with it. The purpose of the drum 34, by means of the rope 38, sheave-pulley 30, and weight 40, is when the pawl is not engaged with the teeth 33 to revolve the ratchet-wheel in the direction of the arrow in Fig. 1 until stopped by some means, and the purpose of the rope 36, pulley 36", and weight 36 is to return the rope-pulley to its normal position when moved from it. The end of the shaft 6 is provided with a crank-pin 37, which in the revolutions of said shaft engages one of the teeth 33 and revolves the ratchet-wheel at each revolution of said shaft the distance of one tooth to the adjoining one. A pawl 41, which is hinged in the bracket-arm 42, engages with the teeth 33 and holds the wheel from backward movement. An adjustable stop 43 is arranged for arresting the downward movement of the pawl below the required point. The pawl is provided with an arm 44, from the outer end of which a rope 45, which runs over the sheave-pulley 46, is arranged, which upon the pulling of its free end by the operator the pawl can be released from the teeth 33. Below the pawl an arm 47 extends downward at an angle for engaging the stop-arm 48, which extends out from the wheel-disk 7, the arm 47 being provided with a hook 49 for engaging with the stop-arm 48 whenever the dog 50 of the pawl 41 falls into the notch 51 in the outer edge of the ratchet-wheel, which it can do wl'ienever the stop 43 is lowered from the position in which it is shown for allowing it to do so. The purpose of said arm, hook, and notch is for stopping the revolution of the wheel at the point desired for arranging the quantitydelivering mechanism for each customer.

Upon the inner side of the ratchet-wheel is a pin 52, arranged in position for engaging the arm 53, which extends outward from the girth 2 of the frame, the ratchetwheel being turned backward until the pin engages the arm at the commencement of weighing each customers liquid which is to be returned to him. Upon the side of the ratchet-wheel adjoining the rope-pulley 35 is fixed a stop-pin 54, and in its path, as the ratchetwheel is revolved toward the right, a similar stop-pin 55 is socured upon the rope-pulley 35. These two stop-pins are shown for the purpose of describing their working accurately, with ach having one flat side, which when no weight is shown by the weight-indicating mechanism are normally in contact. The pin is shown upon the outer side of the rope-pulley,but extends through said pulley and projects so as to be engaged by the similar pin in the ratchetwheel. In practice this pin need not appear upon the outside of the rope-pulley, as it has no function there, but for showing its position with reference to the pin 54 is so shown in the drawings. A rope or connection of some inelastic material, as 56, is secured at one end to the rope-pulley, and its other end is carried upward and away from the machine. in actual use the connection may be protected, as by the pipe 57, so that it is inaccessible by any but one of the factory operatives, so that those to whom the liquid is to be delivered cannot tamper with the weight-indicating mechanism at the outer Oi'ld of said connection. This indicating mechanism consists of a weight-indicating board 53, secured in a suitable position within the factory, (for showing its operation in the present case it is attached to an arm 59, which is secured to the frame of the machine,) where it is not accessible by those to whom the liquid is to be delivered. The scale-board is in the present case provided with two vertical rows of pins and 61, spaced apart equally and forming spaces between them, their distance apart bearing some exact ratio to the distance from one tooth to the other of the ratchetwheel. The pins upon one row are arranged a half-space higher than those of the other LOO row, and one row maybe numbered 5, 15, 25, 35, &c., and those of the other row 10, 2O, 30, a0, 50, 860., up to a hundred. A round bar 62 is fitted to slide vertically between the two rows, its upper end being connected to the connection 56 and its lower end being supplied with a handle 63, and intermediate its ends a pin 64 is provided, which is adapted to fit in between the pins 60 or 61. A band 65, which is secured to the board 58, encircles the bar 62, so that by grasping the handle the operator can move the bar up or down or turn the pin 64 in between the pins of either row.

The buckets of the wheel are each intended to receive and deliver two and one-half pounds of liquid, (wheels of any other capacity may be made and be operated in a manner similar to that herein shown,) the two buckets holding five pounds, which will be delivered at each revolution of the wheel, while the pin 37 will revolve the ratchet-wheel one tooth. The operator wishing to deliver to a customer, say, two hundred and fifty pounds of liquid, releases the pawl from the teeth 33, when the weight upon the rope of the drum 34 will revolve the ratchet-wheel backward until the stop-pin 52 strikes against the stop-arm 53, this starting-point mechanism being used in the present case instead of the notch 51, the

I stop-pin 54 being located upon the ratchetwheel in its correct position relative to the weight-indicating numerals upon the board 58. He then arranges the pin 64 in the space marked 50 on the scale-board, which action will turn the rope-pulley 35 until the stop-pin upon the rope-pulley is distant from the stop-pin 54 upon the ratchet-wheel fifty teeth of said wheel. Multiplying the fifty by live will give two hundred and fifty pounds of liquid delivered. The stop-pin 54L having now engaged the stop-pin 55, the rope or connection from the rope-pulley to the bar 62 will hold the rope-pulley and ratchet-wheel from turning, and consequently the revolutions of theliquid-containing wheel will stop and the delivery of liquid cease until the mechanism is again arranged for another delivery.

66 indicates a milk-can into which the curved sides or chutes 4: direct the liquid as the buckets are emptied.
